Working in St Andrews
As well as St Andrews itself (KY16), we survey in Dundee, Carnoustie and Glenrothes.
Being a smaller town does not change how we work in St Andrews: free survey, written quote, one team. For windowless bathrooms in St Andrews homes, continuous extract that boosts on humidity often works better than a fan tied to the light switch. We check the duct route at St Andrews surveys, because a short, straight run to outside matters more than the fan's headline figure.
Most of Fife is supplied with soft water. Even so, condensation is the bigger problem in any bathroom, and a properly sized extractor is what deals with it. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
- A backdraught shutter and external grille, so cold air does not blow back in
Decisions to make first
Axial, centrifugal or inline
Axial fans suit short, straight runs; centrifugal fans cope better with longer ducts; inline fans sit in the loft and are the quietest in the room.
Noise
Compare the stated noise level in decibels. Inline fans and low-speed continuous fans are much quieter in the room than budget axial fans.
Rules that apply in Scotland
In Scotland, the Technical Handbook also uses 15 l/s extract for a bathroom. A replacement fan rarely needs a building warrant, but forming a new bathroom may.
